ABSTRACT:
An active element substrate and an opposed substrate sandwich a liquid crystal layer to constitute a liquid crystal display device. On the active element substrate, two signal lines respectively charge a pair of pixels that are adjacent to each other in a direction parallel to scanning lines. The two signal lines are provided intensively on a pixel electrode of one of the pair of pixels. In the direction parallel to the scanning lines, a pixel electrode on which signal lines are provided, and a pixel electrode on which signal lines are not provided, are arrayed alternately. This arrangement makes it possible to reduce, while ensuring a wide process margin, the fluctuation of the potential of a terminal to be connected to a pixel electrode (the fluctuation of the potential occurs during OFF-period of an active element due to capacitances respectively provided at superimposed portions of signal lines and a pixel electrode), to simplify the arrangement of signal lines, and to improve the aperture ratio.
